· They are used in grinding of cement raw materials (raw meal) ( limestone, clay, iron ore), cement clinker and cement additive materials ( limestone, slag, pozzolan) and coal. Multicompartment ball mills are relatively inefficient at size reduction and have high specific energy consumption (kWh/t).

These have been used for many years for the less exacting rawmilling process, but recently roller mills, in combination with highefficiency separators, have been used for cement grinding. The grinding action employs much greater stress on the material than in a ball mill, and is therefore more efficient. Energy consumption is typically half that of a ball mill. However, the narrowness of the ...

The grinding mill is coupled with a highpressure roll press in a closed circuit, supported with a highefficiency separator which amplifies the action of grinding. This results in narrow and uniform particle size distribution, along with increased pack size, which accelerates the rate of gain of initial strength, consequently lowering water demand, and achieving higher cohesiveness.

· Grinding efficiency is important for all comminution processes in a cement plant, raw material, coal and cement grinding. While the requirements are basically the same in all cases, cement grinding has a special additional focus, which is workability of the final product and its strength development. Both parameters not only depend on the particle size but to a large degree on the size ...

For cement grinding, the technology development away from ball mills has taken a different route. The development of roller presses in the 1980s took advantage of the benefits of higherpressure grinding and many presses were retrofitted to ball mills as pregrinders. The main benefit was seen at lower Blaines as the first generation of presses suffered from stability problems when attempts ...

Roller presses grind raw materials and cement in a costefficient way. However, the highly dynamic process causes excessive stress on the bearings of the grinding rolls and the two drive trains, which ultimately fail and lead to unplanned stoppages. An online condition monitoring system that uses acceleration sensors can help avoid such stoppages.
